But there are limitations to this research. The main drawback  is that the research was a small cross-sectional study of 80 men. Cross-sectional studies cannot show cause and effect relationships – a randomised controlled trial would be required for this.

It is also important to note that regardless of any differences seen in sperm DNA, none of the 80 men studied actually had reported fertility problems.
